[PATCH] media: imx-jpeg: don't change byteused of queued buffer

From: Ming Qian
Date: Mon Apr 11 2022 - 04:20:33 EST


Don't change the output buffer's bytesused set by user.
Drop allow_zero_bytesused, since it's deprecated.
This should also guarantee it's the application's responsibility
to set bytesused for the output buffer.
